In a swimming mask, a skirt includes a circumferential wall in an annular shape extending rearward from a lens frame, and a seal portion disposed behind the circumferential wall to be brought into contact with a face of a wearer. The skirt also includes a high stiffness annular region disposed rearward apart from the lens frame, extending in both side regions and an upper region of a mask body, and having higher stiffness than stiffness of other part of the skirt.

The present invention provides a strap adjustment device for connecting with a body of a mask. The strap adjustment device comprises a female element, an elastic strap, and a regulating device. The female element is disposed on one side of the body of the mask and has an opening and a slot. The elastic strap has a male element and an adjusting end portion, which is opposite to the male element. The male element has a shape which is substantially corresponding to the female element. The regulating device is connected to the adjusting end portion. When the strap adjustment device is assembled with the body of the mask, the adjusting end portion passes through the opening and the slot before passing through the regulating device in an adjustable manner and being engaged in place by the regulating device. The male element is located in and positioned in the opening.

Disclosed are foldable swimming goggles. The swimming goggles include a left frame body and a right frame body, wherein the left frame body is provided with a supporting block and a limiting block, the supporting block is internally provided with an accommodating groove, a pressing shaft is clamped in the accommodating groove, the lower portion of the pressing shaft is fixedly provided with a positioning rotary wheel, and the right frame body is provided with a steering block. Firm connection of the product is completed through the pressing shaft and the positioning rotary wheel. When the swimming goggles need to be folded, the pressing shaft is pressed to separate the positioning rotary wheel from the steering block, so that the right frame body rotates to make the product folded.

A method of guiding pacing of a strength training exercise includes receiving a selection of a current exercise from a plurality of available exercises, determining an illumination pattern based on a desired pacing for the current exercise, and controlling a lighting system to display a plurality of repetitions of the illumination pattern.

The present invention relates to a floatable breathing device. The floatable breathing device provides includes a head unit, a snorkel, a plurality of receiving passageways, and an internal pathway. The head unit has buoyant properties and includes an ornamental shaped buoyant outer material and an inner shell positioned within the buoyant outer material. The inner shell forms a head receiving section and a protruding section. The head receiving section is received internal to the buoyant outer material and is configured to be contoured to a human head, the protruding section extending from the head receiving section to a vent opening in the outer buoyant material. The snorkel is connected to and extending through the head unit, while the plurality of receiving passageways are disposed about the inner shell and receiving the snorkel such that the snorkel extends through and exits a portion of the head unit at the vent opening. The internal pathway is positioned along a base of the outer buoyant material and extends between the internal shell and the buoyant outer material, passing to the interior of the interior shell through a cutout in a protruding portion thereof and terminating adjacent to the vent opening.

The present invention relates to water goggles, and particularly relates to water goggles having an excellent waterproofing effect, including a rim, a lens sealedly arranged on the rim, an elastic waterproofing ring sealedly arranged on an inside edge of the rim, and a head band whereof two ends are separately connected to the elastic waterproofing ring. The flexible waterproofing ring includes a first connection part connected to the rim, a support part connected to the first connection part, a left-eye contact part connected to the support part and pressed against the rim of a person's left eye, and a right-eye contact part connected to the support part and pressed against the rim of a person's right eye. The left side of the head band is connected to the left-eye contact part, and the right side of the head band is connected to the right-eye contact part.

An adjustable eyewear restraint comprises a first strap having a first adjustment end and a first eyewear coupling end, and a second strap having a second adjustment end and a second eyewear coupling end. The straps are slidably and frictionally engageable to one another to allow adjustment of a length of the restraint by moving adjustment ends of the straps relative to each other. The straps can be slidably interwoven to each other about opening(s) of respective adjustment ends. The opening(s) slidably receive an opposing strap. A strap has a loop, coupleable to eyewear, that comprises first and second edges attached together to form an attachment portion substantially in-line with the first edge. A frictional element is frictionally and slidably coupleable to an earpiece to retain the loop and allow adjustment of a length of an eyewear retainer. Associated systems and methods are provided.

A swimming goggle and a strap structure are disclosed. The swimming goggle includes a goggle main body and the aforesaid strap structure. The goggle main body includes a lens assembly and two lateral connectors which are disposed on two sides of the lens assembly, respectively. The strap structure includes a strap body, an adjusting component and a positioning component. The strap body connects to the lateral connectors of the goggle main body. The adjusting component and positioning component are slidably disposed on the strap body and clamp the strap body. The adjusting component is in front of the positioning component. Therefore, the strap structure can be automatically adjusted to a suitable tightness.

A system includes a minimally intrusive display system (MIDS) configured to be disposed on an eyewear. The MIDS includes a display system and a sensor system configured to provide for a sensor data. The MIDS further includes a processor configured to process the sensor data to derive a physiological measure. The processor is further configured to display, via the display system, the physiological measure, wherein the display system is disposed in the eyewear so that the physiological measure is only viewed when a user of the eyewear turns the user's pupil towards the display system at angle α from a forward direction.

Disclosed are foldable swimming goggles. The swimming goggles include a left frame body and a right frame body, wherein the left frame body is provided with a supporting block and a limiting block, the supporting block is internally provided with an accommodating groove, a pressing shaft is clamped in the accommodating groove, the lower portion of the pressing shaft is fixedly provided with a positioning rotary wheel, and the right frame body is provided with a steering block. Firm connection of the product is completed through the pressing shaft and the positioning rotary wheel. When the swimming goggles need to be folded, the pressing shaft is pressed to separate the positioning rotary wheel from the steering block, so that the right frame body rotates to make the product folded.
